A photon of wavelength 80 nm is absorbed by the electron in the groundstate level of the hydrogen atom. Is this enough energy to ionise the atom? If so calculate the kinetic energy of the free electron.
A photon of wavelength 300 Å is incident upon a hydrogen atom at rest. The photon gives of its energy to the bound electron, thus releasing it from the atom (binding energy = 13.6 eV). Find the kinetic energy in eV and the velocity of the photoelectron.
